Old Folks Home....

One day in a resting home an old lady and an old man were sitting at the coffee table talking. Out of no where the lady said, ‘I bet I can guess your age.’
The old man replied, ‘No you can’t. If you can, go for it.’
So the lady said, ‘OK, take off your pants… now turn around…’
She checks him and continues,‘Ok turn back around, you’re 84 years old.’
The old man in shock, says, ‘how did you know?’
The lady replies, ‘You told me yesterday.’
